POL and POD are the two anchor points of any seaborne operation. POL is where the cargo is loaded, POD where it is discharged, and the POL → POD pair defines the deal’s route.
Choosing ports is not a detail: each pairing carries its own rates, sailing frequency and restrictions, and port charges are usually among the most volatile cost lines of the deal.
Under FOB the seller’s responsibility ends at the POL; under CIF it reaches the POD, freight and insurance included.
